TI-84 Plus C Silver Edition Review: Math in Color!

The new TI-84 Plus C Silver Edition isn't the first color-screen graphing calculator. It isn't even TI's first color graphing calculator, a distinction claimed by the TI-Nspire CX and its sibling the TI-Nspire CX CAS. However, the TI-84+CSE, as we're abbreviating it, is a major milestone in the 17-year-old TI-83 and TI-84 Plus family of calculators. Although it retains the look and feel of the TI-84 Plus operating system, and keeps the familiar case shape and key layout, the outstanding feature of the TI-84+CSE is a bright, glossy color LCD screen. No longer will math and programs need to squeeze into 96 by 64 monochrome pixels; the new screen is 320x240 and can display 65,000 different colors. More »

AP Source: Breedlove likely pick to lead NATO

(AP) ? Gen. Philip M. Breedlove, the top U.S. Air Force commander in Europe, is the likely choice to become commander of all U.S. and NATO forces in Europe, a senior NATO official said Thursday.

The job opened up this week when President Barack Obama's first choice, Marine Gen. John Allen, announced he would retire after 19 months commanding allied forces in Afghanistan in order to attend to his wife's health issues.

The NATO official was not authorized to discuss internal deliberations and spoke Thursday on condition of anonymity.

If nominated and confirmed by the Senate, Breedlove would be the first Air Force general to hold the top NATO job since Joseph Ralston in 2000-2003. Breedlove would succeed Navy Adm. James Stavridis, who has held the post since 2009.

Breedlove, a native of Forest Park, Ga., earned his Air Force officer commission in 1977 through the Reserve Officers Training Corps program at George Tech and has extensive overseas experience, including numerous tours of duty in Europe.

A fighter pilot by training, Breedlove served in Spain and Germany in the mid and late 1990s; in Italy from 2004-05, and in Germany in 2005-2006 and 2008-2009. He has held his current post as commander, U.S. Air Forces Europe, since last July.

Breedlove also served tours in South Korea in 1991-1994 and 2000-2001.

The job of commanding NATO forces in Europe is considered one of the more prestigious command positions for U.S. generals. The U.S. has about 80,000 troops based in Europe.

(AP) ? Sony wants you to know that the PlayStation 4 is coming this holiday season, but not what it will look like.

The Japanese electronics giant talked about its upcoming console for the first time Wednesday and showed what it can do, without actually revealing the device itself during the two-hour event. Presenters played games that were projected on screens in a converted opera house, but the PlayStations themselves were hidden backstage.

"I don't know that the box is going to be something that's going to have a dramatic impact on people's feelings about the game. It will be a color and a size fairly comparable to previous consoles," said Jack Tretton, CEO of Sony Computer Entertainment of America, the U.S.-based arm of the PlayStation business.

"There's a big story to tell here, and it's going to take between now and the holiday season to get all the details out there," Tretton said in an interview.

Tretton said the price of the PS4 hasn't been decided yet, but hinted that it wouldn't be as high as the PlayStation 3 was initially. The PS3 debuted in 2006 with two models for $500 and $600. It now sells for about $300.

The PS4 will be jostling for attention this holiday season with Microsoft's successor to the Xbox. Details on that device are expected in June. Xbox 360 came out a year before PS3 and has been more popular, largely because of its robust online service, Xbox Live, which allows people to play games with others online. Having an event this early allows Sony to grab the spotlight for a few months, though the lack of an actual device was noted by many people on Twitter and elsewhere.

Sony did reveal that the insides of the PS4 will essentially be a "supercharged PC," much like an Xbox. That's a big departure from the old and idiosyncratic PlayStation design and should make it easier for developers to create games. Sony Corp. is using processing chips made by Advanced Micro Devices Inc.

"One of the big challenges we faced in the past was that we created great technology that we handed over to the development community, and they had to go through a learning curve before they could harness it. And when they did, we saw some phenomenal games," Tretton said. "We wanted to lower that barrier of entry and really give them the ability to create tremendous gaming experiences from Day One."

The adoption of PC chips also means that the new console won't be able to play games created for any of the three previous PlayStations, even though the PS4 will have a Blu-ray disc drive, just like the PS3. Instead, Sony said gamers will have to stream older games to the PS4 through the Internet.

Other new features revolve around social networking and remote access. With one button, you can broadcast video of your game play so friends can "look over your shoulder virtually," said David Perry, co-founder of the Sony-owned Internet game company Gaikai. With remote play, you can run a game on the PS4 to stream over the Internet to Sony's mobile gaming device, the PlayStation Vita, which debuted last year.

The goal is to make the PS4 so good at figuring out what games and other content you want that it can download it without being asked, so that it's available when you realize you do want it, Sony said.

"Our long-term vision is to reduce download times of digital titles to zero," said Mark Cerny, Sony's lead system architect on the PS4.

The PS4 is arriving amid declines in video game hardware, software and accessory sales. Research firm NPD Group said game sales fell 22 percent to $13.3 billion in 2012. With the launch of the PS4, Sony is looking to attract people who may have shifted their attention to games on Facebook, tablet computers and mobile phones.

Forrester analyst James McQuivey said Sony is missing the point by building what amounts to an upgraded PS3.

"Sony believes the future will be like the past and has built the game console to prove it," he said. "Tablets and smartphones now engage more people in more minutes of gaming than consoles will ever achieve."

Sony showed an updated controller that adds a touchpad and a "share" button. The controller also features a light bar, which means a new PlayStation camera can more easily track the device for motion control.

The bulk of Wednesday's event was devoted to demos of games for the PS4, including a realistic team racing simulator, "Drive Club," super-powered action sequel "Infamous: Second Son," artsy puzzler "The Witness" and several first-person shooter games, including "Killzone: Shadow Fall." Beyond games, the PS4 will let people create animation in 3-D using a Move motion controller ? all in real time.

Last fall, Nintendo launched the next generation of gaming consoles with the Wii U, which comes with a tablet-like controller called the GamePad. The controller allows two people playing the same game to have different experiences depending on whether they use the GamePad or a traditional Wii remote, which itself was revolutionary when it came out because of its motion-control features.

Judging by Wednesday's event, Sony seeks to improve but not revolutionize game play. The games were updates to existing ones, with improved graphics.

"At the end of the day, this is a device by gamers for gamers," Tretton said. "The games that people go out and spend billions of dollars on are your traditional shooters."

The original Wii has sold more units since its launch than both its rivals, but it has lost momentum in recent years as the novelty of its motion controller faded. Nintendo said it sold 3.1 million Wii Us by the end of 2012. It was a disappointing start for the first of a new generation of gaming systems.

In some ways, notably its ability to display high-definition games, the Wii U was just catching up to the PS3 and the Xbox 360, the preferred consoles to play popular games such as "Call of Duty."

All three console makers are trying to position their devices as entertainment hubs that can deliver movies, music and social networking as they try to stay relevant in the age of smartphones and tablets. The PlayStation online network will have access to Sony's video and music services, as well as Netflix, Hulu and Amazon, with paid subscriptions to those services. People will also be able to access Facebook.

Transcript: Damian Lillard On The Jim Rome Show

Feb 11


Damian Lillard was a guest on the Feb. 11 edition of The Jim Rome Show. You can listen to the interview here, or read the transcript below. Questions and answers are as close to verbatim as one can get from the radio.

Damian great to have you on the show. How are you?

Damian Lillard: "I'm good. How are you?"

Good. Really good. Coming off a tough loss to Orlando last night, so let me ask you about that. You had, well frankly, your worst shooting night of your young career, 1 of 16. You've had a great year but that was a tough night. I know it's a long year and you've got to keep moving. How tough is it to shake something like that and how long does it take to get our of your system?

Damian Lillard: "Um, I think the biggest thing is just moving on. Any time you think about a bad shooting night or any time something didn't go well it tends to carry over. Might have another night like that because I'm thinking about what happened on Orlando, but we played so many games in an 82-game season so you get a quick opportunity to come out and have a better shooting night."

To that point, what's it like? I mean, you're almost at the All-Star break right now. You're accustomed to playing 30-plus games in college. Like, the half of the NBA season, your first half of your first NBA season, how does that feel compared to an entire college season?

Damian Lillard: "I mean, I think the NBA season is a lot tougher because so much of the travel. We might play a home game then the next day we're in New York, then the next day we're somewhere else. So the travel, playing against the best players in the world. You know, I'm playing a lot of minutes. It's a lot tougher than college, but I think some people underestimate the grind of the college season. You have teams that practice hard every day, travel, not as much as the NBA but it's still pretty tough. But I think the NBA is a way bigger challenge."

That's how I take it. Part of the thing is having most fans say 'Yeah, rough life. Rough life. Give me that life!' Five-star hotels, charter flights, this that and the other but I think anybody who just travels, travel alone is exhausting, but if you travel as much as you guys do and you've got to show up and have these runs every night against the best of the best and practice, I can see how that can take a toll. The travel alone would take a toll.

Damian Lillard: "It does. When you're flying until 1 in the morning, 2 in the morning and you have a game there. It's tough to get up for it because you really don't have enough time to recover. The charter flights, it's a lot better than getting on a normal flight, so we're lucky. People want pictures and autographs, things like that, so charter flights makes it easier on us. But at the same time it's still a flight, we still have to get up and play some times on that next day on a back-to-back. It's tough."

Now you find yourself in the middle of a six-game road trip, a really important six-game road trip. In fact, important enough that LaMarcus Aldridge called it a "make or break" road trip. Is that how you entered into it? is that how it feels you, is it a make-or-break trip?

Damian Lillard: "I knew that it was a big trip for us because it could take us in either direction. We could drop under .500 or we (inaudible). I don't think it will break us, but I think if we could get these next two wins it would be good momentum for us going into the All-Star break."

On this trip you're 1-3, got a couple games left. You've got Miami tomorrow night. Talk about how critical that game is at Miami?

Damian Lillard: "It's really big for us. It'll be tough because of how well they're playing but if we can get that one, that would put us at 2-3 on this trip, going into New Orleans, which I think is a winnable game. Every game is but I think that's a very winnable game. If we could finish this road trip .500, 3-3, then we'll be a game above .500, we'll be sitting pretty."

I'm always fascinated by guys, where they start, where they end up. You look at the year you're having right now and it's even more interesting when you consider what you had to get through and what you had to get to to get here. For instance, you start out in high school at St. Joseph's in Alameda, Jason Kidd's alma mater. You weren't seeing a lot of minutes at that time and your parents were paying good money to send you there, yet you weren't getting to play. At that time, what where you thinking about basketball and your prospects?

Damian Lillard: "I mean, I was getting nervous because I was a really big fan of college basketball. I wanted to play in the NBA as much as anybody. But I kinda stepped away from it because I wasn't getting into the game at all at the time. Some times I'd play two, three minutes and other times I wouldn't see the floor. It was tough for me because, everywhere I've been, I wasn't always the best player, but I played. My parents, they're paying money that they don't have to pay for school and I'm not even getting an opportunity to play. It put me in a a tough spot but I just knew that I wouldn't let myself back down from that challenge. I left the school and went back to a public school and I found my place."

And then you flourished. You ended up going to Oakland High in Oakland and averaged more than 20 per game as a senior, but even at that point, like when it seemed like it was all good and was going to work out you weren't getting a lot of attention in recruiting circles, at that point it seemed like you had proven your point but still you weren't getting that attention. What was going on then? How come?

Damian Lillard: "I just think because of the area I was in, it's not a big time area. We don't have a lot of top prospects. I didn't play on a well-known AAU team, so I didn't get the recognition. It didn't bother me; all I wanted to do was get a scholarship. I got on the circuit over the summer and that's when schools started to recruit me and help schools offer me. I just figure what school I went with, make the most of the opportunity. I was blessed to get a scholarship to Weber State. I think my time there was well spent. They really helped me develop myself as a person and a player and I was able to get draft."

What was that like, both on and off the court, the transition from Oakland to Ogden, Utah?

Damian Lillard: "I mean, the type of person that I am, i think Ogden really fit me. It was a laid back, really laid back city, really good people. I met a lot of friends there. I was comfortable as soon as I got there. I had really good relationships with my coaches. It was a lot slower than what I was used to but it really fit my style, really fit my personality. So I enjoyed my time there."

One more thought about your time there. You had a significant test your junior year. There was some talk you might leave early then nine games into that season you broke your foot and you had a lot of time on your hands. At that point what did you do with all that free time?

Damian Lillard: "For about a week, I pouted. I was feeling sorry for myself because I had never had a real serious injury. At this time I was thinking about the NBA, I'm finally performing, scouts are noticing and you break your foot. I pouted for a little bit and then after about a week, week and a half, I met with my coaches and we developed a plan of what I could be doing while I was hurt to get better. I just started to do ball-handling work. I was in the chair, shot on the gun (the name given to the ball return machine used in basketball) from the chair. I was lifting weights six days a week and I watched film of every game I had played up until that point at Weber State. I came up with a list of what I needed to do better based off what I saw and my coach did the same thing. The summer that I was recovering, we broke it all down and worked on those things and I got better at it."

Made the use of the downtime. I'm listening to this and I'm struck by 1) your honesty and then I watch you on the floor and I'm struck by your fearlessness. And there's a story Damian -- you've got to tell me if this is true -- I'm watching you as a player and it seems you're fearless on the court but you admitted if there's one thing that does frighten you, it's statues. And not just statues, but historic statues and it actually goes back to a bad experience at a wax museum. Is that all true?

Damian Lillard: "I was at Madame Tussauds in Las Vegas. I'm walking in the wax museum seeing all the celebrities and I happened to walk into the last room and there's the dead presidents. Martin Luther King. Really huge icons. The Jesus statues and all that kind of gave me shivers. When I saw those people and the music that was playing, it just didn't sit right with me. When I see statues, it kind of bothers me."

Cheap, strong lithium-ion battery developed

Feb. 12, 2013 ? Researchers at USC have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes to provide superior performance.

The new batteries -- which could be used in anything from cell phones to hybrid cars -- hold three times as much energy as comparable graphite-based designs and recharge within 10 minutes. The design, currently under a provisional patent, could be commercially available within two to three years.

"It's an exciting research. It opens the door for the design of the next generation lithium-ion batteries," said Chongwu Zhou, professor at the USC Viterbi School of Engineering, who led the team that developed the battery. Zhou worked with USC graduate students Mingyuan Ge, Jipeng Rong, Xin Fang and Anyi Zhang, as well as Yunhao Lu of Zhejiang University in China. Their research was published in Nano Research in January.

Researchers have long attempted to use silicon, which is cheap and has a high potential capacity, in battery anodes. (Anodes are where current flows into a battery, while cathodes are where current flows out.) The problem has been that previous silicon anode designs, which were basically tiny plates of the material, broke down from repeated swelling and shrinking during charging/discharging cycles and quickly became useless.

Last year, Zhou's team experimented with porous silicon nanowires that are less than 100 nanometers in diameter and just a few microns long. The tiny pores on the nanowires allowed the silicon to expand and contract without breaking while simultaneously increasing the surface area -- which in turn allows lithium ions to diffuse in and out of the battery more quickly, improving performance.

Though the batteries functioned well, the nanowires are difficult to manufacture en masse. To solve the problem, Zhou's team took commercially available nanoparticles -- tiny silicon spheres -- and etched them with the same pores as the nanowires. The particles function similarly and can be made in any quantity desired.

Though the silicon nanoparticle batteries currently last for just 200 recharge cycles (compared to an average of 500 for graphite-based designs), the team's older silicon nanowire-based design lasted for up to 2,000 cycles, which was reported in Nano Lett last April. Further development of the nanoparticle design should boost the battery's lifespan, Zhou said.

"The easy method we use may generate real impact on battery applications in the near future," Zhou said.

Future research by the group will focus finding a new cathode material with a high capacity that will pair well with the porous silicon nanowires and/or porous silicon nanoparticles to create a completely redesigned battery.
